It fits the dv9047EA, dv9095EA, dv9219EA, dv9294EU, and over 229 additional dv9000-series variants. OEM cross-references include HSTNN-IB34, HSTNN-LB33, 432974-001, and 448007-001 among others.\u003c\/p\u003e\n\n  \u003cul class=\"bpw-desc-bullets\"\u003e\n    \u003cli\u003e\n\u003cstrong\u003edv9000 series platform fit:\u003c\/strong\u003e\n    These models share a common 14.4V battery rail, identical connector pinout, and the same BMS handshake protocol — so one cell pack covers the full dv9000 chassis generation without modification.\u003c\/li\u003e\n\n    \u003cli\u003e\n\u003cstrong\u003eBench tested on actual hardware:\u003c\/strong\u003e\n    We ran this cell on a dv9000-series unit and confirmed the BMS completed its handshake, the BIOS accepted the pack without an unknown-device flag, and charge cycling proceeded through all stages correctly.\u003c\/li\u003e\n\n    \u003cli\u003e\n\u003cstrong\u003eFirst-cycle calibration on the dv9047EA:\u003c\/strong\u003e\n    After installing, run one full discharge until the laptop hibernates on its own, then charge uninterrupted to 100%. This resets the BIOS battery learn cycle and clears the inaccurate health warning that commonly appears after a cell swap on this platform.\u003c\/li\u003e\n  \u003c\/ul\u003e\n\n  \u003chr class=\"bpw-desc-divider\"\u003e\n\n  \u003ch3 class=\"bpw-desc-h3\"\u003eBIOS reporting poor battery health immediately after replacement\u003c\/h3\u003e\n\n  \u003cp class=\"bpw-desc-p\"\u003eThe dv9047EA stores battery state data in EEPROM on the old pack. When a new cell is installed, the BIOS reads no historical data and flags the battery as degraded or unknown. This is not a fault with the replacement cell — it is a firmware artefact. Running one full discharge-to-hibernate followed by an uninterrupted charge to 100% gives the BIOS enough cycle data to update its health register. After two to three complete cycles, the health status typically corrects itself.\u003c\/p\u003e\n\n  \u003ch3 class=\"bpw-desc-h3\"\u003eLaptop shutting down at 20–30% charge shown on dv9000 series\u003c\/h3\u003e\n  \u003cp class=\"bpw-desc-p\"\u003eThis happens because the fuel gauge IC is still calibrated to the old cell's discharge curve. At high load — full CPU activity plus display brightness — the new cell's voltage drops faster than the gauge predicts, triggering a protective shutdown before the displayed percentage reaches zero. It is not a faulty cell. Run two full discharge cycles to let the fuel gauge IC map the new cell's actual voltage cliff. After calibration, shutdown should not occur above 5–8% on typical workloads.\u003c\/p\u003e\n\u003c\/div\u003e","brand":"BatteryWeb","offers":[{"title":"Warranty 1 Year","offer_id":43410862407770,"sku":"BWCS-HDV9000NB-1","price":79.99,"currency_code":"USD","in_stock":true},{"title":"Warranty 2 Year","offer_id":43410862440538,"sku":"BWCS-HDV9000NB-2","price":92.99,"currency_code":"USD","in_stock":true},{"title":"Warranty 3 Year","offer_id":43410862473306,"sku":"BWCS-HDV9000NB-3","price":102.99,"currency_code":"USD","in_stock":true}],"thumbnail_url":"\/\/cdn.shopify.com\/s\/files\/1\/0674\/4775\/0746\/files\/BW-CS-HDV9000NB-1.webp?v=1779581377","url":"https:\/\/batteryweb.com\/products\/hp-pavilion-dv9047ea-replacement-battery-144v-4400mah-li-ion","provider":"BatteryWeb","version":"1.0","type":"link"}
